About this part

Product Details

When you're rebuilding the top end of your Chevy Gen 1 Small Block V8, especially when using Edelbrock RPM heads, you need a head gasket that can handle the pressure. This Cometic MLS (Multi-Layer Steel) head gasket is built for that job. It's designed to provide a strong seal between your cylinder heads and block, which is crucial for keeping combustion gases contained and coolant and oil where they belong.

What you get here is a well-built gasket made from multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and different surface finishes. This construction means the gasket can handle the stresses between aluminum heads and either aluminum or cast iron blocks without issue. It has a compressed operating thickness of .040 inches and a bore size of 4.135 inches, specifically suited for many Gen 1 Small Block V8 applications, including a wide range of GM vehicles from the early 80s.

Because it's a Multi-Layer Steel design, this gasket doesn't require any additional sealants, making installation a bit more straightforward. It's a solid option for engines that see a lot of use and need reliable sealing performance.
